CAR ROOF.

Application filed April 4, 1921. Serial No. 458,502.

To all whom it may concern:

Be it known that I, GARTH G. GILPIN, a citizen of the United States, residing at Riverside, in the county of Cook and State 5 of Illinois, have invented new and useful Improvements in Car Roofs, of which the following is a specification.

This invention relates to improvements in car roofs and more particularly to roofs for freight cars of the type known as all metal roofs.

It is an object of this invention to construct a roof of this type in which the roof sheets extend from side to side of the car, are supported on carlines arranged exteriorly of the roof sheets and to which the roof sheets are secured in such a manner as to form water-tight joints. It is a further object of this invention to simplify the construction and assembly of parts by forming the roof sheets from rectangular blanks of the same dimensions and forming the carlines by pressing from rectangular blanks of metal.

The advantages of this construction are that extremely strong roofs of light weight metal may be applied to freight cars without the use of purlins or ridge poles and also provide the maximum amount of head-roomas the carlines supporting the roof sheets on the exterior of the roof. Another advantage is, that the rivets employed for securing the roof sheets to the carlines liejin a horizontal plane and thereby should the rivets become loose in service the rivet holes will not afford ready access for rain or water to drain into the body of the car. An additional advantageis that the peculiar formation of the carlines at the eaves afi'ords a means for ventilation tending to equalize the temperature on both sides of the roof sheets which will reduce the tendency of the metal to. sweat.

While the preferred form of this invention is illustrated upon the accompanying sheets of drawings yet minor detail chan es may be made without departing from t e scope thereof.

In the drawings: 9 Figure 1 is a top plan view of a portion of a freight car roof embodying this invention.

lustrating a modified means of attaching the running board saddles to the carlines.

Figure 6 is'a view similar to Figure 4, il lustrating a modified form of running board saddle.

Figure 7 is a view in section taken on the line 7-7 of Figure 1.

In carrying out this invention the roof sheets 1, extend from side to side of the car body and are bent downward at the eaves 1 over the side plates. In this form the side plates are composed of angle irons 2 with. the upper members arranged in the same horizontal plane. Wooden filler blocks 3 are preferably interposed between the side plates and underside of the roof sheets, the upper and outer surfaces of which are inclined and curved so that the roof sheets extending thereover and therebeyond may rest thereon and then be bent gradually downward over the exterior of the side plates. The eaves ed es and roof sheets are secured to angles 4, w ich in turn are riveted to the side plates, as shown. The side edges of each roof sheet are provided with contin uous upstanding flanges 5, of constant height.

Inverted U-sha ed carlines 6 havin outstanding flanges on their side wal s'are placed over t e spaced apart flanged meet ing edges of the roof sheets with the outare of greater height than the roof sheet flanges and constantly decrease in height from ridge to eaves until the tops of the carlines contact with the tops of the roof flanges over the side plates and the eaves ends of the carlines are extended Wond and bent downward over the side plates with the outstanding flanges following the contour of the body of the roof sheets, and the lower endsof these flanges are riveted to the angle irons securing the roof sheets of the side plates. V

The inverted U-shaped carline being of greatest height at the ridge is strongest where the greatest strength is needed. The outstanding flanges of the carlines increase in width from ridge to eaves proportionately I to the decrease in height of the carline and the carline flanges being of greatest width at the eaves give additional strength to the carlines to reslst the torsional strain of weaving. The carlines not only support the roof sheets but act as seam caps as well, with each side of the carline forming a watertight joint with the adjacent roof sheet. This form of carline is readily pressed from a rectangular sheet of metal.

The running boards 8 are preferably supported on saddles consisting of oblong blocks of wood 9 resting upon the body of the roof sheet and against the side wall of the adjacent carline. It is preferable to secure the wooden saddle 9 by a bolt to the carline side walls, as shown in Figures 1, 4 and 5. As illustrated in Figures land 4 the side wall of the carline over the ridge is provided with an offset 10 below the top of the adjacent roof sheet flange through which the bolt 11 is passed at an angleto the roof sheet as shown. If desired an offset 10 may be struck from the side wall of the carline near the top thereof so that the lower part of the off-set wall will be parallel to the side wall and the bolt securing the saddle block thereto will lie in a horizontal plane, as shown in Figure 5. A metallic running board saddle is shown in Figure'fi which comprises a rectangular plate 12 having one edge secured to a side wall of the carline by the same rivets that secure the carline and roof sheet flange which plate is bent over and rests upon the top of the carline, is riveted thereto, and then extends therebeyond terminating in an upward 0&- set 13 which supports the running boards above the heads of the latter rivets.
